IMPROVEMENT IN EORSIHPWER.

The Scheule referred to in these Letters P'atent and making part of the same.

To all whom it may concern: y

Be it known that we, DENNIS MIcHAELs and J onsY H. CROSKEY, of Hopedale, in the county of Harrison, and State of Ohio, have inventeda new and improved Horse-Power; and we do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part ot this specification.

This invention relates to improvements in horsepowers, having for its object to provide a power especially adapted to hoisting-purposes for elevating hay, freight, building-materials, 85o., to save the loss of time required in backing up the animals, as now employed for hoisting, by drawing a rope through a tackle-block.

The invention consists in arope-winding drum, actuated by a sweep, connected thereto by a latch, counection, which may be disengaged, and allow the rope -to be nnwonnd while the sweep stands still, all ccmbined and arranged as hereinafter more fully described. vFigure 1 represents a plan View of vour improved power, and

Figure 2 represents a side elevation ofthe same.

Similar letters of reference indicate corresponding parts. f

A represents a winding-drum, supported loosely upon a vertical shaft, B, having any prcfelred framing for its support.

G represents a sweep, also supported on the said shaft, and may he either loosely or rigidly connected thereto, as may be preferred, and is provided with a spring-latch, D, arranged to take into the notches of a notched ring, E, secured to the pulley.

The said catch is maintained in constant engagement with the notched ring by the spring E, and the pulley and sweep are thereby connected, so that the former will be operated to wind up the rope when the latter is moved by the animal.

When the -rope has been wound up and the load discharged, the lever D may be disconnected from the notched ring, and the rope drawn down again, or it may be allowed to return by its weight, the drum freely rotating in the opposite direction independently of the sweep.

For convenience, in operating the latch, we connect with it a cord, H, working through an eye supported on the sweep.

By this arrangement the 'animal is required, besides going ahead, to stand only for the return of the rope, which is accomplished quickly.

For more permanence of the sweep, we provide, the stay-ring I supported in suitable studs under the sweep, in a manner to brace it on each side of the axis for steadying it.

Having thus described our invention,

We claim as new, and desire to secure by Letters Patente The combination and arrangement of the drum A, mounted upon the shaft Bin the framing, the notched ring E, sweep C, spring-latch D, cord H, and stay-ring I, as herein described, for the purpose specified.
